How much inventory should I keep?

[Madona]

9. How much inventory should I keep?
Not Too Much
 Dead stock is like spoiled milk. Keep what sells, ditch what doesn't.
 Use Data, Not Gut
 Check what's moving. Stop buying stuff just because you "like it."
 Seasonal Is Key
 If you're selling parkas in July, you've got a storage problem, not a sales one.
